Step-by-step explanation:
Volume of the cube = s^3
s = 9cm
V = 9 * 9 * 9
V = 729 cm^3
d = mass / volume
d = 3645 / 729
d = 5 grams / cm^3

Una cisterna con forma de prisma rectangular mide 1.5 m de ancho, 2 m de largo y 1 m de alto. Si está vacía y se vierten en su interior 150 L de agua por minuto, ¿cuánto tiempo tardará en llenarse?
Step-by-step explanation:
V = 1.5 × 2 × 1 = 3 m³ = 3000 L
tiempo = 3000 ÷ 150 = 20 minutos

Sylvie is mixing concrete for her patio. For every 26.7 pounds of concrete mix, she needs to add 1 quart of water. Sylvie buys 80 kilograms of
concrete mix
1 kilogram 2.2 pounds
How many quarts of water, rounded to the nearest tenth, does Sylvie need to add to 80 kilograms of concrete mix?
Step-by-step explanation:
that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.
so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.
she should add 1 quart of water to every 26.7 pounds of concrete mix.
80 kg = 80×2.2 pounds = 176 pounds.
we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.
176/26.7 = 6.5917603... quarts of water needed.
that would be rounded 6.6 quarts of water.

you have piano lessons every 7 day and tuba lessons every 3 days today you have both lessons.
A. In how many days wil you have both lesson on the same day agian?
B. Not counting today or the day when you have the same lesson again, How many piano lesson will you have in between? Have many tuba lesson will you have in between?
Answer:
A.21 days
B.2, 6
Step-by-step explanation:
(a) In 21 days we will have both lessons on the same day again.
(b) Between each occurrence of having both lessons on the same day again, you will have 2 piano lessons and 6 tuba lessons.
a.
To find out when we will have both lessons on the same day again, we need to find the least common multiple (LCM) of 7 and 3.
The LCM of 7 and 3 is 21. This means that every 21 days, our piano and tuba lessons will align again.
b. Between each occurrence of having both lessons on the same day, you have 21 days. During these 21 days, you will have:
21 / 7 - 1 = 2 piano lessons.
21 / 3 - 1 = 6 tuba lessons.
So, between each occurrence of having both lessons on the same day again, we will have 2 piano lessons and 6 tuba lessons.

The median of the data is: 7
Find the radius of the two other circles
Answer:
We draw the circles on a coordinate system. We know that a circle is has points that are equidistant from its centerpoint. So the point where these circles are tangent is the midpoint between the centerpoints.
We can use the midpoint formula.
M = ((x1 + x2) / 2 , (y1 + y2) / 2)
M = ((-2 + 6) / 2 , (3 + 9) / 2)
M = (2, 6)
These circles will have the same radii.
If we take the distance between the midpoint and (-2,3), we will have the radius of the circle with this centerpoint.
If we take the distance between the midpoint and (6,9), we will have the radius of the circle with this centerpoint.

If tom had 557 oranges and Billy had 676 more oranges than tom. How many oranges does Billy have.
Answer:
billy has 1233 oranges
Step-by-step explanation:
557+676=1233
you add 557 and 676 to figure out how much billy has
you can check your answer by subtracting 1233-557=676
Answer:
Billy has 1233 oranges.
Step-by-step explanation:
This is a simple, they have this many more than this person has, so an example is the B has 1 book, but Alex has a book collection of 10 books. They both have more than one book, but Alex has 10 books in total, with 9 more than B does.
So, for this question, Tom has 557, and Bill had 676 more than him, so that would mean you need to add 676 and 557 together to get 1233 oranges for just Billy. So that would be our answer.

please help, this is geometry
Answer:
Step-by-step explanation:
The formula is the same almost as the previous question you posted.
You want to find the major arc. That's almost the whole circle. If it was the whole circle, the formula would be 2 * pi * r
But we only want a part of it. Just how big is the angle we use in the formula?
A circle has 360 degrees to go around it. We've cut out a slice of it that is 30 degrees.
The remaining part is 360 - 30 = 330
Arc length = angle / 360 * 2 * pi * r
r = 3 m
Arc length = 330 / 360 * 2 * pi * 3
Arc length = 0.9167 * 6 * 3.14
Arc length = 17.27
Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah’s grandma says if she saves that amount, she will give her an additional $50 each month. What are the recursive formula and first term for Sarah’s saving’s?
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

1/6x-1/8=11/12
Answer:
6 and 1/4
Step-by-step explanation:
1/6 x - 1/8 = 11/12
First, let's find the least common denominator (24) to make these fractions manageable to work with: 4/24 x - 3/24 = 22/24.
Next, add 3/24 to both sides: 4/24 x = 25/24.
We can cancel out the denominators at this point to get: 4x=25.
Divide both side by 4, and x = 25/4 = 6 and 1/4 or 6.25
If the digits A, B and C are added, the sum is the two-digit number AB as shown. What is the value of C?
A
B
+ C
______
AB
Answer:
C=9
Step-by-step explanation:
If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)
AB-(A+B)=C
10-(1+0)=9 or 11-(1+1)=9
therefore C=9
Find the value of x
Answer:
Step-by-step explanation:
The exterior angle (shown) is equal to the two remote interior angles ( the ones marked with values in x).
5x + 2 + 5x = 11x - 11 Combine the terms on the left.
10x + 2 = 11x - 11 Add 11 to both sides
10x + 2 + 11 = 11x
10x + 13 = 11x Subtract 10x from both sides.
13 = x
Javonie started a dog walking business over the summer. He walked 8 dogs and earned $160 in July.
He walked 9 dogs and earned $180 in August.
a. How much money did he earn over the summer?
b. How much did he charge per dog in July?
*Determine what you need to find.
*Set up the problem.
*Solve.
*Check.
Answer:
a) $340
b) $20
Step-by-step explanation:
a) in the summer (July and August) he earned 160 + 180 = $340
b) in July he earned 160 ÷ 8 = $ 20
Javonie earned $340 over the summer and he charged $20 per dog in July.
The amount of money he earned over the summer is the sum of the money he earned in July and the sum of the money he earned in August
Total amount earned in the summer = amount earned in July + amount earned in August
$160 + $180 = $340
The amount he charged per dog in July can be determined by dividing the total amount earned in July by the total number of dogs he walked.
Amount charged per dog = amount earned in July / total dogs worked
$160 / 8 = $20
